residuaalkaitselülitiks
A residuaalkaitselüliti, often abbreviated as RCD, is an electrical safety device designed to protect individuals from electric shock. It functions by continuously monitoring the electrical current flowing through a circuit. If it detects an imbalance between the current going out and the current returning, indicating that some current is leaking to the ground through an unintended path, the RCD will rapidly disconnect the power supply. This rapid disconnection is crucial in preventing serious injury or fatality from electric shock.
Residuaalkaitselülitid are typically installed in a building's main electrical panel, protecting multiple circuits. They are distinct
